SAD-IRON.

SPECIFICATION forming part of Letters Patent No. 574,685, dated January5, 1897.

Application filed July 12,1895. Serial No. 555,782. (No model.) I

To all whont if; may concern:-

Be it known that I, PERRY AUGUSTUS HUL- WIGK, a citizen of the UnitedStates, residing at Goshen, in the county of Elkhart and State ofIndiana, have invented a new and useful Sad-Iron, of which the followingis a specification.

My invention relates to sad-irons, and has for'its object to provide aself-heating sadiron provided with a fuel-reservoir exposed to the heatproduced at the burner, whereby the contents of the reservoir arevaporized; furthermore, to provide means whereby the reservoir forms aheat-guard to protect the hand of the operator, and, furthermore, toprovide a simple and efficient arrangement of parts whereby the burnermay be replaced when desired or necessary and is secured firmly inposition when in use.

Further objects and advantages of this invent-ion will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a sad-ironconstructed in accordance with my invention. Fig. 2 is a longitudinalcentral section of the same. Fig. 3 is a bottom plan view of thedeflecting-plate, showing the vaporizing pipe and injector in operativeposition. the base or shell of the iron detached. Fig. 5 is a detailview of the burner detached. Fig. 6 is a similar view of aslightly-modified form of burner.

Similar numerals of reference indicate corresponding partsin all thefigures of the drawings.

1 designates the base or shell of the iron, provided with a cavityforming a combustionchamber, suitable openings 2 being formed in thesides of the combustion-chamber to supply the necessary amount of air tosupport combustion. In this combustion-chamber, near the front end ofthe iron, is formed a parallel-sided seat 3, and in alinement therewith,near the rear end of the iron, is a similar seat 4, the sides of whichare extended up to the plane of the upper edges of the sides of theshell. In rear of the seat 4is a rest 5, having a curved upper surface.

Fig. 4 is a perspective view of The burner isprovid ed at its front endwith aparallel-sided lug 6 to fit in the seat 3, and at its rear endwith a tubular projection or throat 7 to lit in the seat 4, the ends ofthe burnertube bearing against the facing sides of the lugs, in whichsaid seats are formed to prevent endwise displacement thereof. Theburner'is hollow and may be bored or provided with perforations 9, asshown in Fig. 5, or transversely sawed to form kerfs 10, as shown inFig. 6. Arranged upon the base or shell coverin g the combustion-chamberis a deflectingplate 11, which thus closes the top of thecombustion-chamber and is exposed to the flame produced at the burner,and resting upon said deflecting-plate with its lower side spaced fromor out of contact with the upper surface of said plate, is the hollowheat-guard and reservoir 12, said guard and reservoir being held at thedesired interval from the surface of the deflecting-plate by means ofspacing-blocks or projections 13 on the upper surface of said plate.Communicating with the interior of the guard and reservoir is afuel-inlet opening 14, fitted with a screw-plug 15, and alsocommunicating with the interior of said guard and reservoir at its lowerside, and contiguous to the front end thereof, is a pipe or conductor16, having an elbow, of which one arm extends upward through an openingin the deflecting-plate. This pipe or conductor is arranged within thecombustion chamber and extends approximately parallel with theburner-tube to and through the rear end of said combustion-chamber,which is cut away to form an opening for its passage. The rear end ofthis pipe or conductor communicates with an injector 17, having aneedle-valve 18, the injector being adapted to discharge the fuel eitherin a liquid or gaseous state into the throat at the rear end of theburnertube. The valve is controlled by means of the hand-wheel 19,arranged at the rear end of the iron, and the guard and deflectingplateare secured to the shell or base by means of vertical screws or bolts20, said guard carrying a handle 21.

The injector bears upon the rest in rear of the seat 4, and it is heldin contact with said rest by means of a retaining-lug 22, depending fromthe rear end of the deflecting-plate.

In advance of said retaining-lug and also depending from thedeflecting-plate is a stud 23, equal in width with the interval betweenthe sidesof the seat 4 and adapted to bear at its lower end upon theupper side of the tubular projection or mouth of the burner tube,whereby the burner-tube is securely fastened in position and held fromdisplacement.

From the above description it will be seen that the fuel after leavingthe reservoir, where it is heated to a certain extent by the radiationfrom the deflecting-plate, passes through the pipe or conductor arrangedin the combustion-chamber, where it is exposed to the heat from theburner, and is thereby vaporized. The vaporized fuel is discharged bythe injector into the rear end of the burnertube and there is ignited,and the flame is projected against the lower surface of thedefleeting-plate. It will be seen, furthermore, that the guard andreservoir which is interposed between the defiecting-plate and thehandle serves to protect the hand of the oporator and avoid exposure tothe direct radiant heat of the iron.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to Without departing from the spirit orsacrificing any of the advantages of this invention.

Having described my invention, what I claim is 1. In a sad-iron, thecombination of a hollow open-topped base forming a combustionchamber,alined front and rear seats having open upper sides arranged in thecombustionchamber, a burner-tube removably fitted at its reducedextremities in said seats, the ends of the body portion of the burnerbearing against said seats to prevent longitudinal dis placement, aplate detachably secured to the base to close the upper side of thecombustion-chamber, a stud depending from said plate within the chamberto bear upon the burner and hold it in its seats, a reservoir and handlecarried by the said detachable plate, and an injector in communicationwith and 1 carried by the reservoir to discharge fuel into. theburner-tube, substantially as specified.

2. In a sad-iron, the combination of a hollow base forming acombustion-chamber and provided with a front parallel-sided seat 3 and arear seat 4 in alinement with the front seat, a burner-tube provided atits front end with a flat parallel-sided projection 6 to fit in theparallel sided seat 3 and provided at its rear end with a hollowprojection forming a throat and adapted to fit in the seat 4:, a platedetachably secured to the base to close the upper side of thecombustion-chamber and provided with a depending stud to bear upon theupper side of the hollow projection of the burner and prevent verticaldisplacement thereof, a reservoir and a handle carried by the saiddetachable plate, and an injector carried by and in communication withthe reservoir and arranged in alinement With the throat of theburner-tube, substantially as specified.

3. In a sad-iron, the combination of a hollow base or shell providedwith front and rear seats and a rest in rear of the rear seat, aburner-tube provided with terminal projections fitted in said seats, oneof said projections being hollow to form a throat, a deflecting-platecovering the cavity of the base or shell, a hollow guard and reservoirarranged above the deflecting-plate and carrying a handle, and aninjector connected to a pipe or conductor in communication with thereservoir and adapted to discharge fuel into the throat of theburner-tube, said injector being arranged upon the rest in rear of therear seat and the deflecting-plate being provided with a depending lugto bear upon said injector and hold it in place on the rest,substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
